		+
		+	Hello everyone. This is my first wiki contribution, so please bear with me ;-)
		+	There is not much information about the always on problem in the main article so I thought I should share what I just observed:
		+	I have an Hitachi hard drive and used one of their tools to enable power and acoustic management. This tool was on a dos boot disk and when I enabled acoustic management in this environment the fan would turn on and stay on, even when booting into windows afterward.
		+	I left acoustic and power management enabled and reverted the bios settings to default (by pressing F9 in bios) which got rid of the error.

 Hi there,
-I have an IBM R51. Prior to installing Fedora Core 4 I had no problems with the fan, i.e. in Win XP it would turn on and off with no apparent nuisance. With Fedora 4, once it reached a certain temperature (i.e. after a certain period of time, doing the same things), the fan goes on and never off again, of course, unless I shut down the notebook. In a ML someone suggestesd to try openSUSE since they'd be "IBM friendly" and indeed: the 10.0 RC at that time made no trouble: the fan would go on and off according to real needs. Unfortunately, I did upgrade to the latest openSUSE version, only to find the problem repeating again.

 I'm writing this because, in my case, I have the problem only with Linux - instead of what is written on the article side. Maybe it depends on some module?
